TRUSS.

SPECIFICATION forming part of Letters Patent No. 461,038, dated October 13, 1891.

Application filed January 31, 1891 Serial No. 379,794. (No model.)

To (l/ZZ whom, it may CON/06771,.

Be it known that I, ANTON NAIDL, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Iniprovements in Trusses for the Treatment of Hernia; and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which- Figure 1 is a perspective view of a truss embodying my invention, and Fig. 2 is a central section of the same.

Like symbols refer to like parts wherever they occur.

My invention relates to the construction of adjustable spring-ball or spring-pad trusses for the treatment of hernia, either abdominal or scrotal, and has for its object to reduce, simplify, and render effective the mechanism whereby the universal adjustability of the ball or pad is secured.

To this end, one feature of the invention embraces the combinatiom ivith a truss-pad or ball, of a sectional extensible post, one section thereof adapted to slide into the ball, a spring arranged within the ball to support said sliding section, and means for locking the post-sections together, so that no movements of the belt or body of the wearer or of the truss-ball in accommodating itself to the movement of the wearer shall disturb the re lation established between the sections of the extensible post.

A second feature of the invention embraces the combination, with a truss pad or ball, of a post on which the truss-pad is journaled and rotates, and a locking-plate and catch for securing the pad or ball to the post.

There are other minorfeatures of invention, all as will hereinafter more fully appear.

I will now proceed to describe myinvention more fully, so that others skilled in the art to which it appertains may apply the same.

In the drawings, A indicates a portion of the waistband or belt which supports the truss-pad, and in the present instance is shown as of wire, preferably annealed, so as to render it capable of being bent to vary the position of the truss-pad. The free ends of band A (not shown) may be flattened and leathercovered in the well-known way of forming wire aistbands for trusses.

Bindicates a clamp for adjustably securing the ball to the waistband A. This clamp may be composed of a plate 1, a yoke 2, secured to said plate 1 by screws 1 1 or in any other suitable manner and provided with a- 4 indicates a screw-post provided at its upper end with a milled head 4 and near its opposite end with a collar 4, the portion of the post below the collar being threaded to engagethe nut on the end of the screw-rod 5.

By unscrewing the post 4, so as to allow the disengagement of the ratchet-surfaces 31 and 5 the screw-rod 5 may be adjusted to any desired angle with relation to the plate 1 of the clamp B and may be fixed in said position by again tightening up the parts by means of said screw-post 4.

6 indicates a j am-nut arranged on the screwrod 5, said jam-nut preferably of disk form with milled periphery.

7 indicates the pad or ball of the truss, which is hollowed out centrally to-receive a coiled or other suitable spring 8, and also at one side of the center forthe reception of a spring-controlled U belt or catch 9, and 10 indicates the truss-plate, to which the pad or ball 7 is secured by screws or in other suitable manner.

11v indicates a locking-plate, which is preferably in the form of a spool, journaled in the truss-plate 10, the outer circular flange of the spool having a series of holes 11 for the reception of the spring locking-bolt 9, a cen-' tral polygonal-shaped hole or its equivalent being provided for the passage of the tubular internally-threaded spring-post 12, so that the post and its locking-plate may move together and both rotate in the truss-plate 10.

12 indicates a tubular spring-post, preferably of polygonal shape in cross section, adapted to slide endwise on the locking-plate 11, internally threaded for the reception of the screw-rod 5 and provided with collars 12 12 which limit its motion, and one of which 12 may serve as a seat or bearing for the spring 8. If desired, however, the hole in the locking-plate may be round and the tubular post 12 also round, the well-known spline or feather being used to permit the post 12 to move endwise through thelocking-plate while compelling the parts to rotate together.

Pins 13 or equivalent means may be provided to facilitate the rotation of the lockingplate or as a means of holding the lockingplate 11 and tubular spring-post 12 while rotating the pad or ball 7.

The truss-pad being constructed and its parts combined substantially as herein before specified and having been secured to a wire or equivalent waistband A, said band or belt having been first bentor shaped to secure the desired location of the truss-ball 7, the truss ball or pad may be further adjusted, as follows, to meet any special indication: first, inwardly to increase or diminish the distance between the pad or ball 7 and belt or waistband A and the pressure applied by turning the pad and its tubular internally- -threaded post 12 on the threaded rod 5, the parts being subsequently fixed by means of the jam-nut 6; second, at any lateral angle and to bring thepressure on any desired part of the pad or ball by loosening the screw-post 4 until the ratchet-teeth 3 and 5 disengage, moving the pad 7, its tubular post 12, and screw-rod 5 to the desired angle, and then tightening up the screw-post 4: until the ratchets 3* 5 again engage, and, finally, the ball or pad 7 may be adjusted with relation to the person of the wearer by first pressingin the U locking-bolt 9 until the locking-plate 11 is released, then rotating the ball or pad 7 on the locking-plate 11 and post 12 to the desired position, and permitting the locking-bolt to enter the corresponding bolt-hole 11 of the locking-plate 11.

By the construction substantially such as hereinbefore specified, I obtain a universallyadjustable spring truss pad or ball having a wide range in its application to the treatment u of the various classes of hernia.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is-

1. In combination with a truss pad or ball, a sectional extensible post, one section thereof arranged to slide in the truss-ball a spring arranged within the truss-ball to support said sliding section, and means for locking together the post-sections, substantially as and 3. The combination, with a truss-plate, ot'

a locking-plate journaled therein, an endwisesliding post arranged in the locking-plate, and a locking-catch adapted to engage. the locking-plate, substantially as and for the purposes specified.

4. The combination, with a truss pad or ball and its truss-plate, of a locking-plate of spool form journaled in the truss-plate and having a polygonal post-opening, a locking-catch adapted to engage the locking-plate, an extensible post whose cross-section corresponds to the hole in the locking-plate, and a spring arranged in the truss-balland which b ars on the end of the said post, substantially as and for the purposes specified.

5. The combination, with a truss pad or ball, of a movable spring-supported tubular post threaded on its-interior, a threaded rod having at one end a nut with ratchet-face, a clamp having an eye and ratchet-face, and a screwbolt or thumb-screw, substantially as and for the purposes specified.

In testimony whereof I afiix my signature, in presence of two witnesses, this 27th day of January, 1891.

ANTON NAIDL.
